First draw the line AB.
to draw a equilateral triangle
draw circles from both the points of the lineAB(remember that the radius of circle should equal to the length of lineAB)
the point where both the circles are intersecting, name that point C
after joining the points AC and BC
we get the required equilateral triangle.
